Correlation and Path Coefficient Analysis for Various Quantitative Traits in Desi Chickpea Genotypes under Rainfed Conditions in Ethiopia uri icon

abstract

  • Chickpea is rich in protein and micronutrients and plays a significant role in human diet especially asaccompaniment to staples, but grain yields in Ethiopia are still below the crop potential. Field experiments wereconducted during 2007/8-2009/10 to determine relationships among yield and some yield components usingcorrelation and path coefficient analysis in desi chickpea grown under rainfed conditions. Correlation studiesrevealed that seed yield was significantly and positively correlated with days to flowering, days to maturity,number of pods per plant, number of seeds per pod, stand count at harvest, plant height and biomass. The pathcoefficient analysis based on seed yield, as a dependent variable, revealed that biomass had the greatest directeffect on seed yield (0.0146) and followed by stand count at harvest and plant height. Both correlation and pathanalyses indicated that biomass, stand count at harvest and plant height were the major direct contributors toseed yield. Thus, the present study suggests that more biomass production, stand count at harvest and plantheight are major yield factors in selecting high yielding desi chickpea cultivars
